Custom Manufacturing Range
Beyond the standard AWG sizes, Fobos can evaluate custom PTFE single-lumen tubing with:
- Outside diameter: 0.20-20 mm
- Inside diameter: 0.10-18 mm
- Minimum achievable dimensional tolerance: ±0.02 mm
- Continuous coils or specified cut lengths
- Natural translucent or custom colors
- Optional outer-surface etching
Final tolerances depend on the tubing diameter, wall thickness, material and production length.

FAQ
What is PTFE single-lumen tubing?
It is PTFE tubing with one continuous internal channel. It can function as a fluid path, guidewire channel, instrument channel, catheter liner or insulating tube.
What is the difference between single-lumen and multi-lumen tubing?
Single-lumen tubing contains one internal channel. Multi-lumen tubing contains two or more independent channels within one outer profile.
Can Fobos manufacture according to a drawing?
Yes. Fobos can customize the ID, OD, wall thickness, tolerance, length, color and surface treatment according to a drawing or sample.
Is surface etching available?
Yes. Outer-surface etching is available for bonding, over-molding and catheter assembly.
Can the SK5 series produce every AWG size?
No single SK5 model covers the complete AWG 30 to AWG 0 range. The SK5 series produces selected small-diameter and precision specifications. Larger sizes require other suitable SUKO extrusion configurations.
Does Fobos have medical PTFE catheter manufacturing capability?
Yes. Fobos operates under an ISO 13485:2016 medical device quality management system and has a Class 10,000 cleanroom.
Fobos develops and manufactures medical PTFE catheter tubing and precision components, including single-lumen, multi-lumen, thin-wall, liner and etched tubing.
Can PTFE single-lumen tubing be manufactured in a cleanroom?
Yes. Fobos manufactures medical PTFE single-lumen tubing in a Class 10,000 cleanroom under an ISO 13485:2016 quality management system. This capability supports medical device companies that require controlled manufacturing conditions and consistent tubing dimensions.
Can customers purchase equipment for high-volume production?
Yes. Fobos is backed by its parent company, SUKO, which specializes in PTFE processing machinery.
SUKO can configure an extrusion line from the required catheter ID, OD, wall thickness, tolerance and production capacity. The solution can include the extruder, dies, mandrels, sintering system, dimensional monitoring, pulling and coiling equipment.
